MP2491N

32V, 6A, High-Efficiency Synchronous Step-Down Converter with External Soft Start

Description

The MP2491N is a fully integrated, high-voltage, step-down converter. The MP2491N can achieve 6A of continuous output current (I_OUT), with excellent load and line regulation across a wide input supply range.

Constant-on-time (COT) control operation provides very fast transient response, easy loop design, and very tight output regulation. Full protection features include over-current protection (OCP), hiccup current limiting, output over-voltage protection (OVP), and thermal shutdown.

The MP2491N requires a minimal number of readily available, standard external components, and is available in a QFN-13 (2.5mmx3mm) package.
